Abstract: A fluid transfer tube comprises a base, a plurality of external threads, and an annular shoulder. The base is disposed at a first axial end of the tube. The plurality of external threads are integrally formed into at least a portion of the base for securing the base into a boss. The annular shoulder is fixed to an outer diameter of the tube at a first distance from the first axial end, causing the shoulder to contact an outer surface of the boss with the base of the tube at a maximum depth in the receiving portion of the boss to prevent further downward travel of the base.

Abstract: A valve assembly comprises a housing, a movable member, a fixed member, and a resilient member. The seat element has an upstream side, a downstream side, and an outlet port providing fluid communication therebetween, with the seat element fixed in a flow control segment adjacent a valve outlet. The drain element, operable between a first axial position closest to an inlet structure, and a second axial position abutting an upstream surface of the fixed seat element, is retained upstream from the fixed seat element and includes an upstream side, a downstream side, and a plurality of inlet ports through the drain element providing fluid communication therebetween.
